>> the camp here is now overflowing. there are too many people calling out for help. it was built for 90,000 people, but there are already more than 370,000 people here, and the director told me earlier this week that it will reach 500,000 before the end of the year, and there simply are not the resources in place to deal with that. >> just a short, dusty drive away, another camp sits empty, and the refugees crossing the border have no idea it exists. the local authorities allowed the united nations to build this place last year for emergencies. there are no tents. just proper, sturdy houses. it is the permanence of the camp that later annoyed the government. fearing red fiji's might never want to leave, officials shut this place down. for the time being, all these buildings remain shuttered, but make no mistake -- the kenyan government has been very generous in allowing tens of thousands of refugees to cross its borders, escaping drought.
